The video URL(s) will then point directly to a file or files that Flip4Mac can play.
[robg adds: First, sorry for the use of the horizontal scrolling box, but it seemed the best way to make sure the code was presented properly. The easiest way to copy and paste it is to triple-click within the box, then press Command-C. Second, I was only able to make this work in Safari, not Camino or Firefox -- note that this may be an issue on my end. Finally, to actually use the bookmarklet, just load the page containing the videos, click the bookmarklet, then click the video you're interested in watching.]
